Alliances

Warhammer is normally a clash between two armies, but it doesn't have to be a two-player game -- combining several players' armies into alliances lets any number of people join the battle, in whatever bizarre (or narratively justified) combination the available armies allow.

To forge an alliance, split the players into two teams -- they don't need to be equal in number, though it's worth considering the relative size of each side's collection so the game stays balanced. Alternatively, with both players' agreement, a single player may build their force from two different armies, ideally with both sides given the same option. Regardless of how many players are involved, each army in the alliance still needs its own General and Battle Standard Bearer.
